Chapter 1. General Information
The 7207 Model 122 4GB External SLR5 Quarter-Inch Cartridge Tape Drive
(referred to hereafter as the 7207-122 Tape Drive) is an external storage device
that connects to the IBM RS/6000 and provides additional data storage capability.
The 7207-122 Tape Drive includes hardware data compression, which enables
increased storage capacity and data rate.
The 7207-122 Tape Drive features:
Capacity of 4GB per cartridge (8GB at 2:1 data compression)

Tape Drive
The 7207-122 Tape Drive uses single-track linear recording (SLR5) tape drive
technology, and reads and writes to tape cartridges that are compatible with the
following recording standards defined by Quarter-Inch Cartridge Drive Standards,
Inc. (QIC):
A list of compatible tape cartridges and the specific recording standards to which
they are formatted is shown in “Data Cartridge Compatibility” on page 20.
The 7207-122 Tape Drive attaches to any system that uses a single-ended
interface which meets the following standards of the American National Standards
Institute (ANSI):
X3.131-1994, Small Computer System Interface-2 (SCSI-2)
X3T10/855D Revision 15A, Small Computer System Interface-3 (SCSI-3)
Parallel Interface
With the proper cables, you can attach the 7207-122 Tape Drive to a wide or
narrow SCSI bus (for a list of applicable cables, see Chapter 7, “Parts List” on
page 39). You do not need to acquire special device drivers. The 7207-122 Tape
Drive uses the native self-configuring AIX SCSI device driver.
